Soil pH Determination is a vital soil indicator defined as the negative log of hydrogen ion activity. Since pH is logarithmic, the H-ion concentration in the solution increases ten times when its pH is lowered by one unit. The pH … Read more
Soil organic matter (SOM) represents the remains of roots, plant material, and soil organisms in various stages of decomposition and synthesis, and is variable in composition. “Soil Organic Matter Determination” Though occurring in relatively small amounts in soils, organic matter … Read more
Soil hydrogen ion concentration may be a crucial soil indicator, and is outlined because of the negative log of the cation activity. Since hydrogen ion concentration is an index, the H-ion concentration in resolution will increase 10 times once its … Read more
